Learning Poe's Endgame and Crafting

Actually working on my second (the fist one was nuked long ago in 3.14) first endgame T14+ farming build.

Build : Frost Blades (Yes i know, that sucks but i don't wan't to change right now)
Weapon : White wind (Unique) - Dagger only (Nightblade support gem) (Subject to change)
6L gems : Frost Blade - Multistrike - Ancestral Call (subject to chnage for a crit support) - Elemental Damage with Attacks - Added Cold Damage - Nightblade

Constrains :

I play only in Standard and SSF

Path of Building : https://pobb.in/WMeuLSNbrNTc
PoB is not setup for boss dps cause the objective of this build is to farm


Problems with the build :

- Not enough HP
- Not enough Damage Reduction
- Not enough mana
- Not enough evasion
- Elemental resistance is only at 76%
- Chaos resist only at 22%
- Not enough life regen
- Not access to late red maps T14+
- T11 -> T13 doable with lots of frustration and death

Objectives : T14+ farming

What i think i have to do :

Pretty much upgrade all my gear to ilvl 85+

What i have access to :

- Altlas passives 107 points
How it is setup now : More maps, more additional maps, stronbox farming, essence farming, expedition farming
accesss to with partial respecs : Breach - Legion - Delirium

Have access to ilvl 85 gear via Gwennen (faming Astragalies fro rerolls)

What i have never touched or not good with :
- Heist
- Delve
- Bestiary
- Crafting in general

Questions :

1/ What farming methods to use to get the gazillion chaos orbs i need ? (No Trade - No time constrains to farm)
2/ What is the balance of Heist versus Maps in monster power
2 bis and ter / Same goes for Legion and Immortal Syndicate
3/ While i can easily farm T10 maps, i rarely get T11+ (like 1 out of 6) despite having 100% chance of +1 tier map drop via atlas passives. Is it just bad RNG ?

Hard to say without seeing your gear (it's set to private), but I think you're placing far too much importance on item level.
My gear is pretty much junk I slapped together and I still get 105/97/96/60 or something for resistances.

Looking at your pob:
-Go with a jewel for corrupted blood protection
-Take more leech ES/mana/hp nodes since you're in trickster territory already
-Less evade, more armour, run Determination at least
-Run Clarity for more mana regen but keep it at lvl 8 or so, main source of mana should be mana leech since you'll be hitting enemies non-stop anyway

Evade only builds don't work imo

- I allready have corrupted blood protection with a mastery
- More armour is on the table.
- Does gear not translate in PoB links ?
- Mana leech is allready in great shape, i just need more mana.

Major constrain is i don't have any margin for moving nodes on my passive tree without breaking the character, whom is the only one that can farm T10+ for now. When i have another character in mind, it will be easier, but no motivation now to redo the 10 acts.
